TECHNICAL FIELD

The present disclosure relates to the field of intelligent bathroomequipment-related technologies. More specifically, this applicationrelates to an electromagnetic distributor for use with toilets and thelike.

BACKGROUND

A water path distributor is typically provided in a water system ofintelligent bathroom equipment for controlling water paths to achieve awater discharge mode desired by users. A conventional distributortypically controls water paths through engagement of a stator and arotor. Specifically, a plurality of water inlets are formedcircumferentially on the stator and one water outlet is formed on thestator, such that the water outlet and the water inlets are on the samecircle. A stepper motor or the like provides a driving force to make therotor and the stator rotate with respect to each other. When the wateroutlet on the rotor is aligned with one of the water inlets on thestator, one water path is open, while other water paths are in a closedstate, thereby switching different water paths.

However, the above conventional distributor has the following defects.The conventional distributor is suitable for being arranged outside of anozzle (e.g., a nozzle for cleaning bodies), and when the nozzle ispreset with several water paths, it requires the same number of waterpipes to be introduced into the nozzle, which leads to a complexstructure. For existing distributors, a stepper motor rotatescircumferentially to control positions of water outlets to switch amongdifferent water paths, which leads to a long response time and cannotmeet the requirement for a quick switch. Lastly, the water paths of anexisting distributor cannot be turned on or off independently, and onlyone path can be turned on at any moment, which does not meet diversifiedwater discharge requirements.

DETAILED DESCRIPTION

The present application will be further described in detail below withreference to the accompanying drawings and specific embodiments.

FIG. 1 illustrates an exemplary embodiment of an electromagneticdistributor according to the present application. The illustratedelectromagnetic distributor includes a housing 100, a water dischargeassembly 200, and a solenoid valve assembly 300.

FIG. 2 illustrates the solenoid valve assembly 300 of theelectromagnetic distributor according to the present application. FIG. 3illustrates a single electromagnetic switch 310 according to the presentapplication. FIG. 4 illustrates a single plug 230 according to thepresent application. FIG. 5 illustrates an assembly of the housing 100and the spring bracket 240 according to the present application.

FIGS. 1-5 illustrate the housing 100, which includes a water channel 110therein. An inlet of the water channel 110 is located at a first end ofthe housing 100, and an outlet of the water channel 110 extends toward asecond end of the housing 100. The illustrated housing 100 has acylindrical or approximately cylindrical cavity structure with anopening formed on both ends. The water channel 110 may be formed with achannel structure in the housing 100 or may be formed with a water pipein the housing 100. In FIG. 1, the inlet of the water channel 110 islocated on the bottom end surface (the end surface of the first end) ofthe housing 100, and the outlet of the water channel 110 extends to thetop end surface (the end surface of the second end) of the housing 100.

The water discharge assembly 200 is disposed at the second end of thehousing 100 and is configured with a water discharge chamber 210therein. An outlet of the water channel 110 is in communication (e.g.,fluid communication, structural, etc.) with the water discharge chamber210. In a specific embodiment, the water discharge assembly 200 includesa spring bracket 240 and a splitter plate 250. The spring bracket 240and the splitter plate 250 together define the water discharge chamber210. At least one water outlet 220 is located on a face of the waterdischarge assembly 200. As shown in FIG. 1, four water outlets 220 areformed on a face of the water discharge assembly 200 furthest away fromthe housing 100, and each of the water outlets 220 is provided with aplug 230. The plug 230 is located in the water discharge chamber 210.The water outlets 220 are used to guide one or more paths of water flowto the inlet of a nozzle of a downstream module of the electromagneticdistributor, respectively. In at least one embodiment, the springbracket 240 is disposed at one side close to the solenoid valve assembly300, the splitter plate 250 is disposed at one side away from thesolenoid valve assembly 300, the water outlets 220 are formed on thesplitter plate 250, and the plugs 230 are mounted on the spring bracket240. The plugs 230 are connected to the spring bracket 240 via elasticmembers 260. An elastic force of the elastic members 260 causes theplugs 230 to seal the corresponding water outlets 220.

FIG. 4 illustrates the plug 230 including a rubber gasket 231 and ametal sheet 232. The rubber gasket 231 is mounted above the metal sheet232. The rubber gasket 231 is used to seal the water outlet 220, and themetal sheet 232 is used to fix the rubber gasket 231 in the waterdischarge chamber 210. In at least one such embodiment, the metal sheet232 is connected with the spring bracket 240 via the elastic member 260.The elastic member 260 may be a torsion spring.

An exemplary implementation process includes the following steps. Thewater discharge assembly 200 is not limited to the discrete structureset forth in the above embodiments, but may also be an integrally formedcavity structure. The cavity structure is in communication with thewater channel 110, such that water flow in the water channel 110 canflow into the cavity structure. The water discharge assembly 200 mayfurther be used to seal the second end of the housing 100 to preventwater from flowing from other positions than the water outlets 220 toaffect the water spray effect.

The solenoid valve assembly 300 is disposed inside the housing 100. Thesolenoid valve assembly 300 includes at least two electromagneticswitches 310. The electromagnetic switches 310 correspond one-to-one tothe plugs 230, and each of the electromagnetic switches 310independently controls an open/close state of a corresponding plug 230.

FIGS. 1-9 illustrate an embodiment which includes four water outlets 220to correspond to four plugs 230 and four electromagnetic switches 310.It should be understood that the electromagnetic distributor accordingto the present application is not limited thereto, and other numbers maybe set up as needed.

In a non-operating state, each of the plugs 230 seals the correspondingwater outlet 220 when acted on by the elastic member 260. When any oneof the electromagnetic switches 310 is turned on, the corresponding plug230 is configured to open, such that the water discharge chamber 210 isin communication with the air via the opened water outlet 220 and waterin the water discharge chamber 210 can be sprayed out via the openedwater outlet 220.

With the electromagnetic distributor according to the embodiment of thepresent application, the solenoid valve assembly 300 can independentlycontrol each of the water outlets 220 to open or close, therebyachieving a water discharge mode desired by a user. Such electromagneticdistributor can be disposed inside a nozzle, for instance, inside anozzle for cleaning bodies, and does not need to be arranged separatelyoutside the nozzle. Moreover, a plurality of water paths can be combinedand switched by only introducing one water pipe into the nozzle, therebysimplifying the overall nozzle structure. The implementation of rapidswitch and control of on and off of each water path in the nozzle ascontrolled by the solenoid valve assembly 300 greatly shortens theresponse time and can meet the requirements of rapid switch and control.In addition, a plurality of electromagnetic switches 310 are integrated,which can divide one path of incoming water into a plurality of paths ofwater discharge, and the plurality of paths can be controlledindependently with no mutual interference, thereby meeting diversifiedwater discharge requirements.

FIG. 6 illustrates a water flow path of the electromagnetic distributoraccording to the present application. FIG. 7 illustrates theelectromagnetic distributor in a non-operating state according to thepresent application. FIG. 8 illustrates a single path of theelectromagnetic distributor in an open state according to the presentapplication. FIG. 9 illustrates two paths of the electromagneticdistributor in an open state according to the present application.

As shown in FIGS. 1-9, the electromagnetic distributor according to anembodiment of the present application further include an inlet end cap400. The inlet end cap 400 is disposed at the first end of the housing100. The inlet end cap 400 is configured with a water incoming chamber410 thereon. The water incoming chamber 410 is in communication with theair, and the inlet of the water channel 110 is in communication with thewater incoming chamber 410, such that the water outside can enter thewater channel 110 via the water incoming chamber 410 and enter the waterdischarge chamber 210 via the water channel 110. When the plug 230 isopen, the water flow can be sprayed out from the corresponding wateroutlet 220. The inlet end cap 400, the housing 100, and the splitterplate 250 can be ultrasonically welded together.

The inlet end cap 400 can seal the first end of the housing 100 toprevent water from entering the housing 100 at positions other than thewater channel 110. The inlet end cap 400 can seal the first end of thehousing 100 also to prevent impacts by incoming water on the solenoidvalve assembly 300 and other parts in the housing 100. The shape of theinlet end cap 400 matches the shape of the first end of the housing 100and the connection of the two may enhance the overall structure rigidityto prevent deformation.

As shown in FIG. 5, the spring bracket 240 may be assembled onto thehousing 100 by means of hot melt posts 120. This method can greatlyincrease the assembly speed and improve the assembly efficiency.

FIG. 10 illustrates an assembly of the plug 230 and the spring bracket240 according to some embodiments of the present disclosure. Withreference to FIGS. 7-10, the spring bracket 240 is formed with at leasttwo mounting grooves 241, the plugs 230 are correspondingly, one-to-one,mounted inside the mounting grooves 241. The metal sheet 232 of the plug230 may be disposed in the corresponding mounting groove 241 via theelastic member 260. The elastic member 260 is a torsion spring in theembodiment shown. A first end of the metal sheet 232 (the left end ofthe metal sheet 232) is movably connected to a first inner wall of themounting groove 241. This movable connection can constantly keep thefirst end of the metal sheet 232 at the connection position withoutmoving along with a second end of the metal sheet 232, e.g., a jointconnection, a rotating shaft connection, etc. The second end of themetal sheet 232 (the right end of the metal sheet 232) is connected to asecond inner wall of the mounting groove 241 via the elastic member 260,or torsion spring. The second inner wall is opposite the first innerwall. In a non-operating state (the state as shown in FIG. 7), theelastic force produced by the torsion spring pushes the second end ofthe metal sheet 232 to the corresponding water outlet 220, such that therubber gasket 231 seals the corresponding water outlet 220. The entireplug 230 appears to be in an inclined state, i.e., a distance betweenthe first end of the metal sheet 232 and the water outlet 220 is greaterthan a distance between the second end of the metal sheet 232 and thewater outlet 220. In an operating state (the state as shown in FIG. 9),the metal sheet 232 rotates about the first end when acted on by theelectromagnetic force, such that the second end of the metal sheet 232moves in a direction away from the water outlet 220, causing the rubbergasket 231 to leave the water outlet. The water outlet is opened, andthe plug 230 is in an overall flat and straight state, i.e.,substantially parallel to the spring bracket 240. This design has thefollowing advantageous effects. The plug 230 does not move as a whole inthe control process, but has one end always fixed, which preventsdislocation and leads to a more reliable structure and a long servicelife. The movement of only one end requires an electromagnetic forcesmaller than that required by the movement of the whole piece, leadingto easy control and reduced consumption of electric energy.

In the implementation process of the present application, the solenoidvalve assembly 300 may be implemented with various solenoid valves orother devices capable of controlling a magnetic field. An exemplaryimplementation manner is described below.

As shown in FIGS. 1-3, each of the electromagnetic switches 310 in thesolenoid valve assembly 300 include a switch bracket 311 and a coil 312wound around the switch bracket 311 (the structure as shown in FIGS. 2and 3). A magnetic force is generated when the coil 312 is energized,and the magnetic force acts on the corresponding plug 230 to control anopen/close state of the plug 230. The switch bracket 311 may beimplemented by a plastic bracket, and the coil 312 may be implemented byan enameled wire. The enameled wire winds around the plastic bracket toform the coil 312. Two solder pins 313 may be provided on the plasticbracket for connection with two ends of the enameled wire, respectively.In use, a voltage is applied on the two solder pins 313 to energize thecoil 312, thereby forming a desired electromagnetic field and convertingthe magnetic pole direction of the electromagnetic field by controllingthe current direction.

As shown in FIG. 1, a control circuit board 320 may also be included.Two solder pins 313 on each of the electromagnetic switches 310 aresoldered to the control circuit board 320, and the control circuit board320 controls the energizing state of the coil 312. The control circuitboard 320 may be implemented by an existing logic circuit, which inputsa forward or reverse voltage to the coil 312, thereby forming magneticfields having different magnetic pole directions. A wire bundle 330 goesout of the control circuit board 320, and the wire bundle 330 may extendout via the inlet end cap 400 and be connected to an externalcontroller. A user may input a control signal via the controller tocontrol the water pattern.

Each of the coils 312 are inserted with a static iron core 350, andmagnetic sheets 360 are mounted on the solenoid valve assembly 300. Theembodiment shown in FIG. 8 includes a side magnetic sheet 360 and abottom magnetic sheet 360. Every two groups of the electromagneticswitches 310 are connected with the bottom magnetic sheet 360 at thebottom, and then soldered to the control circuit board 320. The staticiron core 350 and the side magnetic sheet 360 are assembled in acorresponding counterbore of the housing 100. The plug 230 is fixed bythe spring bracket 240 and the side magnetic sheet 360, but can rotateabout the spring bracket 240. This design can better control thegenerated magnetic field and achieve precise control. The principlethereof is similar to that of conventional solenoid valves and will notbe elaborated herein.

The multiple arrows in FIG. 6 illustrate the entire path of the waterflow. An external water flow enters the water channel 110 in the housing100 via the water incoming chamber 410 on the inlet end cap 400, andenters the water discharge chamber 210 via the water channel 110. Nowater is sprayed out when the water outlets 220 are closed. When thewater outlets 220 are open, the water flow in the water dischargechamber 210 is sprayed out via the opened water outlets 220.

Each of the coils 312 are configured with a permanent magnet 340.Through the cooperation between the permanent magnet 340 and theelectromagnetic switch 310, long-time power-on can be prevented duringthe water discharging process. The role and effect of such a design willbe described in detail below.

The operating principle and operating process of the electromagneticdistributor according to some embodiments of the present disclosure willbe described in detail below through specific examples.

The non-operating state of the electromagnetic distributor is shown inFIG. 7. With reference to FIGS. 1-9, in the non-operating state, all theelectromagnetic switches 310 are in the closed state, i.e., none of thecoils 312 is energized and no electromagnetic field is generated. Atthis moment, each of the plugs 230 seals the corresponding water outlet220 when acted on by the corresponding elastic member 260, and the waterflow cannot be sprayed out from any one of the water outlets 220 afterentering the water discharge chamber 210.

In the operating state, such as the open state of a single path as shownin FIG. 8, the water outlet 220 at the right in FIG. 8 is open. When auser chooses this water pattern, the control circuit board 320 firstapplies a forward pulse to the coil 312. The electromagnetic forcegenerated by the electromagnetic switch 310 attracts the correspondingplug 230 downwardly, such that the plug 230 leaves the correspondingwater outlet 220. The water outlet 220 is opened, and the water flowbegins to be sprayed out from the water outlet 220. When the plug 230 isattracted to a corresponding position, the control circuit board 320stops the input of the forward pulse, the coil 312 is powered off, andthe electromagnetic force disappears. At this moment, the magnetic forceacted on the plug 230 by the corresponding permanent magnet 340 isgreater than the elastic force provided by the elastic member 260, andthe plug 230 is stilled attracted by the permanent magnet 340 at theopen position. When the user needs to terminate this spray or this sprayis automatically terminated through a control program, the controlcircuit board 320 applies a reverse pulse to the coil 312, and theelectromagnetic switch 310 produces an electromagnetic field opposite tothe previous magnetic pole direction. The electromagnetic field producedat this moment has an opposite magnetism to that produced by thepermanent magnet 340, thereby offsetting the magnetic force acted on theplug 230 by the permanent magnet 340. The elastic force provided by theelastic member 260 is greater than the magnetic force produced by mutualoffset by two magnetic fields, thereby popping up the plug 230 toultimately block the water outlet 220.

If the user chooses a combined water pattern, including but not limitedto the dual-path water pattern as shown in FIG. 9, the electromagneticswitches 310 corresponding to the multiple paths are simultaneouslyenergized for a short period, thereby opening a plurality of wateroutlets 220 to achieve the combined water pattern. The specificprinciples are similar to what is described above. Therefore, theprocess of a combined water pattern will not be described in detail.

Based on the same invention concept, the embodiments of the presentapplication further provide a toilet 500, as shown in FIG. 11, includinga nozzle 502 for cleaning bodies, and further including theelectromagnetic distributor 504 according to any one of the aboveembodiments, wherein the electromagnetic distributor is disposedco-axially inside the nozzle, an outer wall of the housing 100 isattached to an inner wall of the nozzle and is configured in a sealedmanner. The first end of the housing 100 faces an upstream direction ofthe nozzle, and the second end of the housing 100 faces a downstreamdirection of the nozzle.

The water flow from the upstream direction outputs a water patterndesired by a user to the downstream direction through theelectromagnetic distributor. The specific control process of theelectromagnetic distributor has been described in detail above and willnot be elaborated herein. The toilet according to the embodiments of thepresent disclosure simplifies the internal structure of the nozzle,thereby improving the assembly efficiency. When the user switches to adifferent water pattern, the response time is quick and the wait time isshortened. Multiple water paths may be independently controlled to openor close, thereby achieving combined water patterns, providing moreoptions for the user and improving the user experience. It should beunderstood that the electromagnetic distributor according to theembodiments of the present disclosure not only can be used on a toilet,but also can be used on other bathroom products and other productsrequiring water spray or liquid spray.

With the electromagnetic distributor and the toilet according to anembodiment of the present application, the solenoid valve assembly 300can independently control each of the water outlets 220 to open orclose, thereby achieving a water discharge mode desired by a user. Suchelectromagnetic distributor can be disposed inside a nozzle and does notneed to be arranged separately outside the nozzle. Moreover, a pluralityof water paths can be combined and switched by only introducing onewater pipe into the nozzle, thereby simplifying the overall nozzlestructure. The implementation of rapid switch and control of on and offof each water path in the nozzle as controlled by the solenoid valveassembly 300 greatly shortens the response time and can meet therequirements of rapid switch and control. In addition, a plurality ofelectromagnetic switches 310 are integrated. The plurality ofelectromagnetic switches 310 can divide one path of incoming water intoa plurality of paths of water discharge, and the plurality of paths canbe controlled independently with no mutual interference, thereby meetingdiversified water discharge requirements.
